MARK A. PENNEY, OF DES MOINES, lOlVA, ASSIGNOR TO lVILLlA-U L. CAE- PEUTER, OF SAME PLACE.

WIRE-=TWISTING MACHlNE.

SPECIFICATION forming part of Letters Patent No 291,765, dated January 8, 1984.

(No model To all whom it may concern:

Be it known that I, MARK A. PENNEY, a citizen of the United States, residing in Des Moines, in the county of Folk and State of Iowa, have invented a new and useful Improvement in ire-Twisting Machines, of which the following is a specification.

This improvement relates to the twisters used more especiallyin connection with barb-fence to machines; and it consists in the novel features hereinafter set forth.

In the accompanying drawings, Figure 1 is a side elevation of my invention, with the twistingi'rame' turned to a vertical position.

Fig. 2 is a plan view of the same. Fig. 3 is a partial longitudinal section upon the line 00 00 of Fig. 1. Fig. 4 is a partial cross-section upon the line 7 y of Fig. 1, and Fig. 5 is also apartial cross-section upon the linezzof Fig. 1.

Similar letters of reference indicate like parts wherever used in the drawings.

In the operation of my machine the wire passes first through the hollow journal thereof at A, thence over asprocket-wheel, A, located 2 5 near the mouth of the journal, and thence to a traversing and distributing sprocket wheel,

B. This sprocket-wheel has a laterally-extended hub upon one side, whereon a worm,

b, is cut, and it revolves upon a sleeve, 0,

c loosely encircling the shaft D, which is supported at either end in the twisting-frame A The sleeve 0 is made integral with or attached to the arm 0, and the wheel B is confined thereon by the collar and set-screw c c. In the 3 5 arm 0 is journaled a shaft, E, lying longitudi nally in the frame, upon one end of which shaft is a worm-wheel, e meshing with the worm b, and upon the other end whereof is a pinion,

' c, which gears with rack E, secured upon the 0 cross-bar B" of the frame. A collar, 6, upon the extreme end of the shaft E, as said shaft rotates, bears against the inner surface of an elliptical guide, E, surrounding the rack E.

The operation of the distributor-wheel in this construction is as follows: The wires, as

they pass to the spool, operate the wheel B in precise accordance with the speed at which they pass over the same. The operation of this wheel operates also the worm, and the worm operates its wheel and the pinion e. The pinion e, by reason of its engagement with the rack, traverses said rack, and carries with it in that movement the distributer-wheel and all the intervening parts. hen the pinion reaches the end of the rack, it revolves around 5 5 the end thereof, being caused to do so by the guide E, and thence travels back in the opposite direction, its teeth meshing with the opposite side of the rack, thus giving said pinion an endless path, in which it moves always in the same direction, and enabling me to dis pense with the reversing devices usually employed in twisters and fliers. The change in the angle of the pinion-shaft due to the endless path motion at the pinion end is accommodated by the attachment of the arm 0 to the shaft D, such attachment permitting both oscillationand sliding.

The spool is placed upon the shaft F, and secured to the head F, one face of which is toothed to mesh with a pinion, f, (in broken lines) upon a shaft, f, actuated by pulley f receiving power by chain, belt, or otherwise from the pulley f upon the journal G at this end of the frame. The tension-exerting devices are applied to the pulley G in any of the usual ways, said pulley being loose upon the journal, and said pulley f being fast to said tension-pulley, and likewise loose upon said journal.

H H are the gears, whereby the frame is operated.

My invention permits the use of a plain shaft to support the distributingwheel, instead of the right and left threaded one usually employed.

I claim 1. The combination, with a distributingwheel adapted to be actuated by the wire passing over it, and aplain shaft for supporting the same, of devices actuated from the distributing-wheel, for imparting a to-and-fro movement to said wheel, substantially as specified.

2. The combination, with the rotating distributing-wheel and a plain shaft for supporting the same, and upon which it slides to and fro, of the frame, the rack stationary the motion of the wheel is communicated to said pinion and collar, substantially as specified.

5. The combination of the distributer-wheel, the worm on the hub thereof, the arm provided with the sleeve on which the wheel rotates, and said sleeve, with the shaft D, the worm-wheel,the pinion, the rack,the surrounding guide, and the collar, acting in conjunction with the guide, substantially as specified.
